I did run into something similar compiling some weird fpga program. I
ran out of memory and swap making a 200kb executable, with so many
includes and linked libraries that it needed over 150Megs to build.
That wasn't available, so it got killed by the kernel when I ran out of
swap, and reported
out of virtual memory (It was out of real memory too - I had free
running).
/# include no-expert-here warning
If it holds onto all memory and swap, I suspect something odd in the
code.
